Flame Retardants & Smoke Suppressants

Chemical and mineral flame retardants belong to a diverse family of naturally occurring and man-made chemical compounds. These retardants reduce the flammability of polymer formulations. Fire can occur in many different situations and across innumerable applications. As such, flame retardants can be found in everything from electronic devices to household furnishings.

Flame retardant additives are commonly used in the thermoplastic, thermosets, textiles and coatings industries. The right flame retardant additive for your application depends on several factors:

  • The polymer being used
  • Compounding process conditions
  • Temperatures
  • Service requirements for the finished part

The Advantages of Flame Retardants

Flame retardants are organized by different classes depending on their chemistry, particle size, composition and applications. Generally, they can be separated into mineral, organohalogen compound and organophosphorus compound categories.

Flame retardants offer a powerful advantage for many industrial applications, but they should be selected with the utmost care and safety.

Brominated Flame Retardants

Albermarle: Saytex

Brominated flame retardants are incorporated as halogen donors. Typical applications include plastics, cable insulation and textile.

Chlorinated Paraffin

Dover Chemical Corp.: Chlorez & Paroil

Primary applications of chlorinated paraffin in the polymer industry include flame retardancy and extension of primary plasticizer systems.

Mineral Flame Retardants

Albermarle: Martinal & Magnifin
R.J. Marshall Company: Ground ATH

Mineral flame retardants are used when non-halogen flame retardant systems are needed. They release water at elevated temperatures.

Silicone Based Additive

Dow Corning®: Resin Modifier (4-7081) & Si Based Additive (11-100)

Resin modifiers & additives reduce die drool and heat release rate during the extrusion process. They also improve hydrophobicity and increase LOI.

Silicon Dioxide

Elkem: Sidistar & Sidishield

Silicon dioxide improves dispersion of high loadings of mineral flame retardants.  It also serves as a partial antimony oxide replacement.

Smoke Suppressant Blends

R.J. Marshall Company: Ctec & Htec

Smoke suppressant blends are custom formulated to meet specific compounding applications.
